Abstract: Les médicaments à effet immédiat contenant un dérivé d'acide 2-arylproprionique pharmacologiquement actif comme nanosol pharmaceutiquement applicable ont un temps d'action et une biodisponibilité considérablement améliorées de la substance active. Les dérivés de l'acide 2-arylpropionique, par exemple l'ibuprofène, le flurbiprofène et le kétoprofène, qui sont peu solubles dans un milieu aqueux, sont présents dans un nanosol stabilisé dans de la gélatine sous une forme qui permet à ces substances actives d'être complètement et rapidement résorbées dans l'estomac. On prépare le système de dispersion colloïdale divulgué composé d'un dérivé de l'acide 2-arylpropionique en choisissant une gélatine ou un dérivé de la gélatine en fonction de leur point isoélectrique (PIE), de manière que leur PIE soit adapté à la charge des particules du dérivé de l'acide 2-arylpropionique, ce qui donne une charge neutre lorsque la gélatine ou son dérivé est combiné au dérivé non dissout de l'acide 2-arylproprionique à un pH déterminé. La gélatine ou son dérivé sont convertis en une forme sol aqueuse, leur pH est fixé selon le PIE de la gélatine à la valeur qui stabilise les nanoparticules du dérivé de l'acide 2-arylpropionique à une charge approximativement ou totalement neutre. Avant ou après cette dernière étape, le dérivé de l'acide 2-arylpropionique est dissout dans le sol aqueux de gélatine  ou une solution de dérivé de l'acide 2-arylpropionique est mélangée au sol de gélatine aqueuse.

Granted: 2007-09-25
Abstract: Methods and compositions for treating urogenital tumors, and in particular, cancer of the prostate, bladder, and kidney, with BCNT, are disclosed. Any boron-containing compound that is sufficiently lipophilic to pass through the appropriate urogenital membranes in a quantity high enough to achieve therapy on irradiation with low-energy neutrons can be used. Carboranyl-containing nucleosides and oligonucleotides are particularly suited for use in BNCT of urogenital tumor s. Preferred compounds include 5-carboranyl-2'-deoxyuridine (CDU) and 5-o-carboranyl-l-(2-deoxy-2-fluoro-.beta.-D-arabinofuranosyl)uraci l (CFAU). Nucleosides and oligonucleotides bearing an -O-[(carboran-1-yl)alkyl]phosphate, S-[(carboran-1-yl)alkyl]phosphorothioate , or Se-[(carboran-1-yl)alkyl]phosphoroselenoate in place of the (carboran-1-yl)phosphonate moiety can be used. Oligonucleotides of specific gene sequences that include one or more 3', 5'-linking- (carboran-1-yl)phosphonate moieties can also be used in antisense therapy in the selective modification of gene expression. Compounds can be used in urogenital BNCT therapy that contain boron clusters as a means to enhance lipophilicity wherein the boron is not enriched in 10B, but instead, in the 11B isotope. The therapy is accomplished by administering the boron-containing compound by any appropriate route, including by intravenous injection, oral delivery or by catheter or other direct means, in such a manner that the compound accumulates in the target tumor. After desired accumulation of the compound in the tumor, t he site is irradiated with an effective amount of low energy neutrons.

Abstract: A radio channel initial transmission scheme for a mobile communication system which is capable of reducing an unnecessary interference with respect to the other radio channels as well as an unnecessary consumption of a battery of a mobile station. In the present invention, this is realized by not carrying out a transmission of the unnecessary general information during an initial period of a radio channel set up. More specifically, only the constantly necessary information among radio channel transmission signals is initially transmitted from a transmitting side of the base station and the mobile station, at a time of setting up a radio channel between the base station and the mobile station, and then the constantly necessary information and the general information other than the constantly necessary information are subsequently transmitted from the transmitting side, after a receiving side of the base station and the mobile station becomes ready to receive the radio channel properly.
